integrated core I/O.
The standard I/O connectivity is integrated on the rx2660 system board and includes an integrated HP 8 Internal Port SAS (Serially
Attached SCSI) Host Bus Adapter, two 1000Base TX LAN ports, an RN50 graphics port, three USB v2.0 ports, and one general RS
232 Serial Port. Additionally, there is a standard Integrity iLO2 Management Processor with a rear RS 232 Serial Port.
Each port of SAS Host Bus Adapter can be connected to a SAS hard disk drive. SAS is a point to point architecture, compared to
Ultra320 SCSI which is a bus based architecture. With SAS, each disk has its own individual 3 GB link.
possible 'integrated' RAID controllers for the rx2660: AD248A#106 refers to the embedded SAS RAID controller. AD248A#130,
AD248A#530 and AD248A#540 refers to an add-in SAS p400 Smart Array card which occupies a 'private' slot (does not use one
of the system's PCI slots).
HP UX, OpenVMS, and Linux support the integrated HP 8 Internal Serial Attached SCSI host bus adapter (AD248A#106), which
supports a maximum of two RAID 1 volumes (2×2 HDDs) and a disk for global hotspare, for a maximum of five disks in RAIDed
arrays. The remaining three disks (of the maximum eight disks that are supported) can be accessed normally, but not configured for
RAID. Please note that MirrorDisk/UX is available for software mirroring on all HDDs in HP UX based systems, as HP Volume
Shadowing (software Raid 1) for HDDs in OpenVMS based systems. Windows does not support this integrated HP 8 Internal Port
SAS Host Bus Adapter. All Windows systems must order the HP 8 Port SAS Smart Array P400 Serial Attached SCSI (SAS) Controller
Card (AD248A#130, AD248A#530, and AD248A#540), which is also available as an optional choice for HP UX, OpenVMS, and
Linux systems. The HP 8 Port SAS Smart Array P400 Serial Attached SCSI (SAS) Controller is accommodated via a dedicated PCI
Express slot, which provides up to 1.3 GB/s of sustained bandwidth.
The HP 8 Port SAS Smart Array P400 Serial Attached SCSI (SAS) Controller Card supports RAID 1, 5 and 6. All eight disks can be
configured with this card for RAID 1, 5 and 6 in any combination. RAID 1 requires two identical HDDs, RAID 5 requires three
identical HDDs, and RAID 6 requires four identical HDDs. Factory configuration of a RAID set is available. Please see rx2660
Ordering Guide for details. The two standard 1000Base TX LAN ports support Wake On LAN.
There is a mandatory choice of only one of two internal I/O card cage options, each option provides three I/O slots for I/O
expansion within the system enclosure. The two I/O card cage options are an all PCI X Card Cage and a Combo Card Cage. The
all PCI X Card Cage provides two PCI X 266 MHz 64 bit I/O slots and one PCI X 133 MHz 64 bit I/O slots (AD246A). Please note
that this option (AD246A) is not supported with Windows based systems. Each slot of the AD246A has its own dedicated bus and its
own independent I/O channel. An independent channel provides improved I/O performance and error containment. Independence
protects each I/O card from bus hangs or extended latencies due to the failure or high bandwidth demands of other I/O cards.
Independence also ensures that each I/O card can achieve maximum throughput. The two 266 MHz slots provide 2.1 GB/s of
sustained bandwidth, while the one 133 MHz slot provides 1.1/GB/s of sustained bandwidth.
The Combination Card Cage (AD247A) provides two PCI Express x8 slots and one PCI X 133 MHz 64 bit I/O slot. Please note that
the AD247A is required for Windows based systems. Each slot of the AD247A has its own dedicated bus and its own independent
I/O channel. The two PCI Express slots 2.6 GB/s of sustained bandwidth, while the one 133 MHz slot provides 1.1 GB/s of
sustained bandwidth.
All I/O slots are keyed for 3.3V I/O cards. 5V cards are not supported in the HP Integrity rx2660. OLAR (On-line add/remove)
operations are not supported on the rx2660.
The chart below provides further details on the standard I/O.
